T 0 all lw om t may concern Be it mown that I, CHARLES B. SCHOEN- MEHL, citizen of the United States, and resident of lVaterbury, in the county of New Haven and 4State of Connecticut, have 1nvvented certain n'ew and useful Improvements in Primary Batteries, of which the following is a specification.

-This Ainvent-ion relates to a simple and improved form of bausticsolution battery, adapted :tork track circuitwork and employed for operating bells, block signals and the like.

It further relates to primary batteries of that class wherein OXid of copper and Zinc are employed in said solution and arranged one above the other, distant from each other.

A further purpose of the invention is to so arrange the elements that they will be insulatively connected and supported one from the other and finally to form the ele-l ments so that they may be readily inserted into or removed .from the jar and also rigidly supported therein' so as to prevent disassemblement. y

Similar characters of reference will be found to designate like or corresponding parts throughout the several figuresl and of` which, l

Figure l, shows a sectional perspective View of myl present' form of track circuit battery with the elements resting upon the bottom of the jar. Fig. 2, is a plan view of the assembled electrodes shown in Fig. l, and, Fig. 3, shows a further sectional perspective View of my battery, t-he assembled electrodes of which are shown supported from the top or cover of the jar instead of being supported 'from the bottom of the jar as shown in Fig. l. l

Referring in detail to-the characters of reference marked upon the drawings, 5 represents a battery jar which as shown in Fig. l, has no cover, but whichin Fig. 3, is provided with a cover 6. The positive elec- ,trode 7 and negative electrode 8 are connected and .supported one from 'the other through the medium of a frame@ which 1s preferably made .of a single strip pt sheet metal that is bent and formed to connect the electrodes one above the other, distant from each other. This frame includes the two vertically disposed side portions 10-10, a horizontal top cross or bridge portion ll. The lower ends of the sides l0 are bent and secured to the metal receptacle l2 in a way to form legs lll. `One or more additional legs 14, may also. be secured to this receptaclel to better support the intermediate side portions to said receptacle as isclearly shown in Fig. l.' The receptaclelZ is formed in part ot' a sheet metal pan having a perforated sheet metal tpp or covering 15, and is filled with oxid of co'pper as shown, and thus constitutes. the negative electrode.V As shown in the drawings .this electrode is arranged adjacent to the bottom of the jar and supported in the frame 9 before mentioned, and which frame in turn may be supported fromthejbottom'otthe jar as shown in Fig.pl, or from the cover as'sho'wn in Fig. 3. f

I preferably eniploy the circular itorm of' zinc velectrode 7, which is hung frornthe cross portion 1l of the trameeby means of a pair of short rods 1G, secured Ato the zinc and extended upward therefroman'd pass-- .ing through insulating washers 17 of the frame whereI they are secured in said position by means of nuts 18. The held wire 19 connecting with the Zinc pole of the battery, may be attached to one of t-hese rods 16 by means of a suitable nut as shown. The centrally arran'gedfrod 20 is secured to the cross member ll ot-t'he frame and to it is attached the second field wire 21 by means ot' which the electricalconnection with the negative electrode 'is formed through the said frame. The side .members l0 of the frame are bowed Vout to yieldably engage the opposite side portions 'of the jai to support the element central a'nd rigid therein. In .F ig. 3, theterminal 20 also serves as' a suspending rod, by means .of which the assembled electrodes are hung rom'the cover G of the jar, and may be attached to or removed from the 'cover by the operation of the nuts upon the rod, and thus made toA hang free of theJjar-asi shown. The perforatedside of the negative electrode receptacle is obviously arranged adjacent to, but below the zinceelectrode and is'thus arranged to` properlyiconnect therewith inI the effective operation of the bat'- tery, and further .prntect-s the copper from any sediment from the zinc element above.

vHaving thus' described my invention what I claim and ent is .L In a track circuit battery of the class described, the combination tot a rectangular desire to secure by Letters. Patshaped supporting frame, a negative elecv 1raV and distant therefrom, and secured tothe i upper part of the frame.

2. In a track circuit battery of the class described, the combination of a.negative elecl trode, a zinc electrode, a supporting frame connect-ed Wit-h and supporting each of the said electrodes and having longitudinally disposed strips that are bowed out to engage the side Walls of a jar to center and support the electrodes, and means for supporting the frame and electrodes Within a jar.

3. In a primary battery of the class described, the combination of a suitable supporting frame adapted to engage the inner Walls of a jar, a horizontally arranged zinc elect-rode hung from the frame, a horizontally arranged metal container supported upon the frame and having its side adjacent to the ziiic perforated, a filling of oxi'd of copper in the container, and means for supporting the frame Within a jar.

4. In a track circuit battery of the class described, the combination of a negative electrode comprising a flat metal container with perforations in one side and arranged in the bottom of a battery jar, a filling of oxid of copper Within the xcontainer, a zinc electrode arranged above the negative electrode and distant therefrom, and a metal strip connected with both electrodes for supporting one electrode from the other.

5. In a primary battery of the class described, the combination of a suitable supfv lio porting frame, a zinc electrode'mounted in the frame, a perforated. metal container also supported in the frame and having means for supporting it in a battery jar, a filling of oXid of copper in the container, and means for supporting the zinc electrode from and above the negative electrode Within a J 6. In a primary battery of the class described, the combination of a frame adapted to be supported in a battery jar and to engage its side walls, a zinc elect-rode mounted in the upper part. of the frame, a metal container supported in the lower part of the frame and jar and having its side adjacent,

to the zinc perforated, a filling of copper oxid in the container. l i

7. In a primary battery of -the class de` scribed, the combination of a frame adapted to be supported uponthe bottom ofa jar and also engaging the side walls of a battery jar, a zinc electrode mounted mathe frame, a metal container supported 1n the lower part of the frame and jar and having its side adjacent to the zinc perforated, a filling of copper oXid in the contamerhand means for supporting the frame Within a ar. l A J Signed at Bridgeport in the county of Fairfield and State of Connecticut this 24 day of April A. D., 1912.
